Note 1: Absolute Maximum Ratings are those beyond which the safety of a
device may be impaired.
Note 2: All currents into device pins are positive; all currents out of device
are negative. All voltages are referenced to device ground unless otherwise
specified.
Note 3: All typicals are given for VCC = 5V, C1 = C2 = CVCC = 1µF,
CVDD = CVEE = 3.3µF tantalum capacitors and TA = 25°C.
